Nine months of heat pushes a lot of air through your ducts
Your furnace runs September through May here, nine months of the year. That's nine months of air moving through the same ductwork, carrying dust and whatever else settles in the return before it gets pushed back out through the vents.
Winter nights averaging 4°F mean the furnace runs hard and often, and a house sealed up against that cold recirculates the same air again and again. Dust builds up along the duct walls, and over time it thins out the airflow reaching each room.

- How often should air ducts be cleaned?
- There's no fixed number of years that fits every home. If anyone in the house has allergies, or you've had work done that left dust behind like a furnace swap or a remodel, that's a reason to do it sooner. Homes with pets or a smoker in the house also tend to need it more often. Look inside a vent cover with a flashlight. If you see a layer of dust or debris in there, it's time.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now. If you can see dust buildup, if there's a musty smell when the furnace kicks on, or if someone in the house has allergy symptoms that ease up when they're away from home, cleaning is worth doing. If none of that applies and your filter changes are up to date, you may not need it yet. A contractor can look at your ducts and tell you honestly whether there's enough buildup to matter.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock debris loose from inside the ducts, then pulls it out before it can resettle. This covers the supply and return ducts, the grilles and registers, and usually the coil and blower housing inside the furnace or air handler itself. The furnace filter gets replaced as part of the job since it's already open. A thorough cleaning reaches every duct run, not just the ones near the main trunk.
